alsa-project/alsa-ucm-conf issue #333 was opened from kmarty:
Hi,
I have Arturia MiniFuse 2 card allowing playback/capture sample rate in range 44100 - 192000. But using channel name (e.g. `Mic/Line/Inst 1 (L)`, `Main Output L/R`) created by UCM, it offers 48000 only (and in case o playback, it offers S15_LE only).
Looks like something is lost when `SplitPCM` macro is used or so (I have absolutely no idea what's going on here).
Is there any possibility to make it work as it should?

Without matching UCM profile the in/outs offers the full range (but everything is mapped as "surround" 4-channel):
